If NOTHING at all is specified, in ANY part of the problem (traffic
engineering or otherwise), then I would suggest putting at as high a speed
as possible! But make SURE that you read through the whole test, and make
sure that there's nothing catching you. If it is clearly not specified, I
think I would be paranoid about it. :)

I just wanted to get this clear once and for all. If in a lab, the bandwidth
of your WAN links (FR, Serial, ISDN, ATM) is not specified, then what should
you put in?? Clock rate is not even specified, so at the moment I just put
in clock rate 64000, which I can easily be using 128000 or 256000 depending
on whether the hardware supports it.
So if bandwith and clock rates are not specified, then what number should I
plug in?
Thanks
Albert

The correct thing to do is ALWAYS make the bandwidth reflect whatever the
clockrate is in that interface.

like serial links always default to a T1
1.544Mbps for routing protocol cost calculations.
Another question that has been in the back of my mind is that when should
the bandwidth statement be entered into the interface? From various labs
(eg. fatkid), and sources they say that it is a good idea to always include
the bandwidth statement for all WAN interfaces (FR, Ser, BRI, ATM). But if
there were no specifications for what bandwidth to put on the interfaces,
then what can you do?
I guess if the bandwidth statement was left off, then they would default to
T1 and that should be ok.

whatever you assign the clockrate, that's your total bandwidth. Try to do
tftp w/ 128k than try w/ 2048k you will see the difference. clockrate=bw.
